E6: Cycle Skip A cycle skip is detected
while processing the
signal for
measurement
This is usually due to poor
signal integrity, possibly
because of bubbles in the
pipeline, sound absorption
by very viscous fluids, or
cavitation
If this error is caused by changes in
flow rate, this error will be auto
corrected when flow rate stabilizes
after initial acceleration. But, if the
error stays refer to “Fluid and Pipe
Problems” section to correct any
issues. Check Threshold Peak
percentage, and gather required
diagnostics data before contacting
Panametrics
E15: Active Tw The Active Tw
measurement is invalid
A transducer, cable is
damaged, or a transducer
needs to be re-coupled. This
may also be due to
incorrect programming, or
extreme process
temperatures
Refer to “Transducer Problems”
sections to correct any issues. In case
you are unable to clear the errors,
gather required diagnostics before
contacting Panametrics
E22: Single
Channel Accuracy
One of the
measurement
channels is in error
One measurement channel
is in error; accuracy of the
measurement may be
compromised because the
meter might be using a
sister chord substitution
Check individual channel errors, refer
to this table for recommended
actions to correct channel errors
E23: Multi Channel
Accuracy
Two or more
measurement
channels are in error
Two or more measurement
channels are in error;
accuracy of the
measurement may be
compromised because the
meter is using a sister chord
substitution
Check individual channel errors, refer
to this table for recommended
actions to correct channel errors
E27: Invalid K-Table K-Table is invalid The entered K-table is
invalid
Check the K-table values and ensure
the Velocity or Reynolds Number in
the table is in ascending order
E28: Software Fault Software malfunction This is a Software
malfunction.
This condition is not self-recovering
and will not automatically correct
itself. Try power cycling the meter. If
error persists after power cycle,
contact Panametrics factory.
E29: Velocity
Warning
The measured velocity
exceeds programmed
warning limits
This error may be caused by
incorrect programming,
poor flow conditions and/or
excessive turbulence
Make sure the actual flow rate is
within the programmed Warning
limits (Refer Programming Chapter).
Refer to “Fluid and Pipe Problems” and
“Transducer Problems” sections to
correct any issues
E31: Not Calibrated The flow meter has not
been calibrated
The flow meter has not been
calibrated at the factory
and hence not making
measurements. Please
contact Panametrics
factory
The condition is not self-recovering
and will not automatically correct
itself. Contact Panametrics factory to
get more information on the meter
setup
